Best raspberry pi ups power bank hat For 3B/3B+/4B

12, Jul 2021 | Raspberry Pi | 1 comment

Today we will be looking at the best Raspberry Pi UPS power bank hat for your Raspberry Pi 4. UPS stands for uninterruptible power supply.

Why use a Raspberry Pi UPS power bank hat?

If you live in an area prone to power cuts or even if you want to secure your Raspberry Pi 4 from unexpectedly powering off.

A UPS device can be fitted to your Raspberry Pi 4 and in the event, the mains power supply cuts out the UPS will automatically take over and power the Raspberry Pi 4 from an attached battery bank keeping the Raspberry Pi 4 online. It can even send a graceful shutdown command to your device to make sure a clean shutdown is performed. This is important for data integrity.

It is very important to use a UPS device when you are using your Raspberry Pi 4 for any data handling or storage. Either for backups or media storage.

The power banks and UPS devices we recommend today will work to keep the Raspberry Pi 4 powered on.

To add UPS functionality to external mains-powered USB devices we recommend going with a UPS Power Brick see our guide here

Pisugar2 Pro Portable Review:

Raspberry Pi UPS power bank hat

The PiSugar2 Pro is compatible with the Raspberry Pi 3B/3B+/4B. There are also other models available for the Pi Zero. Not a conventional hat but works the same way. Connecting to the Pi via the GPIO pins.

Step 1: Hardware Installation:

This UPS power bank hat was easy to assemble. It took 4 screws that secured the UPS hat to the bottom of the Raspberry Pi 4.

It came with pre-soldered pins on the Pisugar2 Pro which aligned perfectly with the underneath of the Raspberry Pi 4’s GPIO pins. This placement has an added bonus as it frees up the GPIO pins to be used from the top for other projects.

The battery has a strong magnet that clips onto the hat securing the battery to the hat and Pi

Step 2: Installing Software and Configuring the Pisugar2 Pro settings.

The software that comes with the Pisugar2 Pro was easy to install on Raspberry Pi OS by running this one line of code.

curl | sudo bash

The PiSugar2 team has supplied great documentation on their Github which can be found here:

Once you select your model the software installation will complete.

Once the software is installed you can access the PiSugar GUI dashboard over the network. From here you can configure the Pisugar2 Pro.

Open a browser and navigate to:

http://<your raspberry ip>:8421

From within the dashboard, you can Enable “Schedule Wake Up” and “Safe Shutdown” as well as program “Custom Button Functions“.

Our Verdict:


  • Easy To Assemble.
  • Comes With Custom Software
  • Network GUI Dashboard
  • Safe Shutdown
  • 5 – 7 Hours – Idle Battery Life
  • 3 – 4 Hours – watching 1080p movies


  • Makes The Pi Have A Larger Form Factor
  • Might Not Fit Into Standard Cases

Apart from the larger form factor, this hat gives to our Raspberry Pi 4. (The PiSugar team has supplied an Open-source 3D Case on the homepage of their website which you can get 3D printed online).

There are not many cons with this device. We have tested it extensively and in all our test shutdowns and powercut simulations, the Pisugar2 Pro worked flawlessly.

The programmable custom button function test worked great. In our test, we set our Pi to shut down when we manually double pressed the hat’s button.

This concludes our product review.

    If my house loses mains power, will the ups take over without powering down the pi. Then, can it recognise when the battery is at say 30% capacity and safely shut down the pi. Is it then able to re boot the pi when mains power is restored, maybe by testing for mains power every hour say.

    If mains power is restored before the 30% power down will it return to normal monitoring?

    Hope this not to complicated to understand.
